The novel preparations of dyeing assistants can be prepared merely by stirring together the
said components (A), (B), (C) and, if ~lop,iate, (D), homogeneous mixtures beingobtained which are distinguished by good stability on transport and storage. The dyeing
assistants according to the invention are, in particular, very stable at elevated temperatures
of up to 130C, when they are employed in dyebaths.
The dyeing assistant according to the invention is used, in each case depending on the
dyestuff, in the dyeing of textile material containing synthetic fibres, in particular
polyester fibres. The dyeing process is carried out in each case in a customary manner.
The dyeing assistant according to the invention is introduced slowly and with stirring into
an aqueous liquor, after which the liquor is prepared for dyeing by adding the dye.
Accordingly, the present invention also relates to a process for dyeing synthetic material,
in particular polyester fibres, by means of disperse dyes. The process comprises dyeing
this material in the presence of the mixture of a~si~nts according to the invention.
The amounts in which the combination of assistants according to the invention is added to
the dyebaths range from 0.5 to 10 %, preferably 1 to 5 %, of the weight of the goods.
Examples which may be mentioned of fibre m~tçri~l, in particular textile material, which
can be dyed in the presence of the novel mixture of assistants are cellulose ester fibres,
such as cellulose acetate and triacetate fibres and, in particular, linear polyester fibres.
Linear polyester fibres are to be understood here as meaning synthetic fibres which are
obtained, for example, by the condensation of terephthalic acid with ethylene glycol or of
isophthalic acid or terephthalic acid with 1,4-bis-(hydroxymethyl)-cyclohexane, and also
copolymers formed from terephthalic and isophthalic acid and ethylene glycol. The linear
polyester which has hitherto been employed almost exclusively in the textile industry
consists of terephthalic acid and ethylene glycol.
The fibre materials can also be used in the form of mixed fabrics, with each other or with
other fibres, for example mixtures of polyacrylonitrile/polyester, polyamide/polyester,
polyester/cotton, polyester/viscose and polyester/wool.
The textile material to be dyed can be in various stages of processing. For example, the
following are suitable: loose material, piece goods, such as knitted or woven fabrics, and

~0~332
_,
- 10-
yarn in package or muff form. The latter can have a package density of 200 to 600 g/dm3,
in particular 400 to 450 g/dm3.
The disperse dyes to be used, which are only very slightly soluble in water and are present
in the dye liquor for the most part in the form of a fine dispersion, can belong to a very
wide range of classes of dye, for example the acridone, azo, anthraquinone, coumarin,
methine, perinone, naphthoquinoneimine, quinophthalone, styryl or nitro dyes.
The amount of dyes to be added to the liquor depends on the tinctorial strength desired; in
general, amounts of 0.01 to 10, preferably 0.05 to 5, per cent by weight, relative to the
textile material employed, have proved successful.
Depending on the textile material to be treated, the dyebaths can contain, in addition to the
dyes and the mixture of assistants according to the invention, oligomeric inhibitors,
anti-foaming agents (for example silicone oils or ethylene-bis-fatty acid amides),
non-creasing agents and, preferably, dispersants.
The dispersants serve, in particular, to achieve good dispersion of the disperse dyes. The
dispersants which are generally customary in dyeing by means of disperse dyes are
suitable.
Suitable dispersants are preferably sulfated or phosphated adducts of 15 to 100 moles of
ethylene oxide or, preferably, propylene oxide onto polyhydric aliphatic alcohols having 2
to 6 carbon atoms, for example ethylene glycol, glycerol or pentaerythritol or onto amines
having 2 to 9 carbon atoms and containing at least two amino groups or one amino group
and one hydroxyl group, and also alkylsulfonates having 10 to 20 carbon atoms in the
aL~yl chain, alkylbenzenesulfonates having a linear or branched alkyl chain with 8 to 20
carbon atoms in the alkyl chain, for example nonylbenzenesulfonate,
dodecylbenzenesulfonate, 1,3,5,7-tetramethyloctylbenzenesulfonate or
octadecylbenzenesulfonate, and also alkylnaphthalenesulfonates or sulfosuccinic acid
esters, for example sodium dioctylsulfosuccinate or sodium di-2-ethylhexylsulfosuccinate.
Ligninsulfonates, polyphosphates and, preferably, formaldehyde condensation products
formed from aromatic sulfonic acids, formaldehyde and phenols which can be
monofunctional or bifunctional, for example from cresol, ~-naphtholsulfonic acid and
formaltlehyde, from benzenesulfonic acid, formaldehyde and naphthalenesulfonic acid,

from naphthalenesulfonic acid and formaldehyde or from naphthalenesulfonic acid,dihydroxydiphenyl sulfone and formaldehyde, have proved particularly advantageous as
anionic dispersing agents. The disodium salt of di-(6-sulfonaphth-2-yl)-methane or
tri-(6-sulfonaphth-2-yl)-methane is preferred.
It is also possible to use mixtures of anionic dispersants. Normally, the anionic dispersants
are present in the form of their alkali metal salts, ammonium salts or amine salts. These
dispersants are preferably used in an amount of 0.5 to 8 g/l of liquor.
The dyebaths can also contain customary additives, preferably electrolytes, such as salts,
for example sodium sulfate, ammonium sulfate, sodium or ammonium phosphates, sodium
or ammonium polyphosphates, metal chlorides or nitrates, such as calcium chloride,
magnesium chloride or calcium nitrates, ammonium acetate or sodium acetate and/or
acids, for example mineral acids, such as sulfuric acid or phosphoric acid, or organic
acids, preferably lower aliphatic carboxylic acids, such as formic acid, acetic acid, citric
acid or oxalic acid. The acids serve, in particular, to adjust the pH of the liquors used in
accordance with the invention, which, as a rule, is 4 to 6.5, preferably 4.5 to 6. In certain
cases, however, it is also possible to carry out dyeing in an alkaline range (pH 7 to 10).
Dyeing is advantageously carried out from an aqueous liquor by the exhaustion process.
The liquor ratio can, accordingly, be selected within a wide range, for example 3:1 to
100:1, preferably 7:1 to 50:1. The temperature at which dyeing is carried out is at least
70C and, as a rule, is not higher than 140C. It is preferably within the range from 80 to
135C.
Linear polyester fibres and cellulose triacetate fibres are preferably dyed by the so-called
high-temperature process in closed, and preferably also pressure-resistant, equipment at
temperatures of over 100C, preferably between 110 and 135C, and, if ~plupliate, under
pressure. Examples of suitable closed vessels are circulation machines, such as package or
beam dyeing machines, winch becks, nozzle or drum dyeing machines, jet or muff dyeing
m~chines, paddle machines or jiggers.
Cellulose acetate fibres are preferably dyed at temperatures of 80-85C.
The dyeing process can be carried out in such a way that the material to be dyed is either
first treated briefly with the mixture of assistants and is then dyed or, preferably, is treated

2009382
-
- 12-
~imlllt~neously with the mixture of assistants and the dye.
It is preferable to allow the material to be dyed a preliminary run of 5-10 minutes at
40-80C in the bath which contains the dye, the ~ ul~ of assistants and, if appro~liate,
further additives and whose pH has been adjusted to a value of 4.5 to 10, to raise the
temperature in the course of 15 to 45 minutes to 110 to 135C, preferably 125-130C, and
to keep the dye liquor for 15 to 90 minutes, preferably 30 to 60 minutes, at this
temperature.
The dyeings are finished by cooling the dye liquor to 60 to 90C, rinsing the dyeings with
water and, if a~plopliate, reduction clearing them in a customary manner in an alkaline
medium under reductive conditions. The dyeings are then rinsed again and dried. Uniform
and intense dyeings which are additionally distinguished by good fastness to light and
good fastness properties to rubbing are obtained on synthetic fibre material, in particular
on linear polyester fibres. The dye liquor remains stable during the dyeing and no deposits
are formed in the interior of the dyeing machines.
